Databinding - Lozalized FallbackValue/TargetNullValue etc

In my Windows Phone 8 C#/XAML .NET 4.5 App I'm using databinding from ViewModel, which is working fine.

What I'd like is for a lozalized string from LocalizedResources to be displayed as a content of a button in the following cases:

How could this be achieved?

What I've tried to do is:

(omitted TargetNullValue, since the way to do it is probably going to be the same)

(for presentation purposes, i set the resource to be Applicationtitle)

<Button ... Content="{Binding Something, FallbackValue={Binding Path=LocalizedResources.ApplicationTitle, Source={StaticResource LocalizedStrings}}}" ... />

But what I get is text like System.Windows.Text.Data.Binding...(can't read more since it's out of screen).

Did some googling/"stackoverflowing" and found something with valueconverters for WP7, that got me a bit puzzled.

(And added C# tag because I've got a feeling this is not going to be solved just by adding the right "property" to a tag/value to a "property", although I'd appreciate it to be)

I'm pretty sure you cannot apply binding to the FallbackValue. A very simple workaround is to check for null within your 'Something' property.

private string _something;

public string Something
{
    get { return _something ?? AppResources.ApplicationTitle; }
    set
    {
        _something = value;
        OnPropertyChanged("Something");
    }
}
